4 Application filed. March 2, 1922.

To all whom it may concern: N

Be it known that 1, JAMES E. LYNci-i, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Pole Puncturing Machines; and I do hereby de clare the following to bea full, clear, and exact description of the invention, such will enable others skilled, in the art to which it appertains to make and use the same.

Particularly, myv present invention relates to pole puncturing machines of the general type disclosed and claimed in the application of IHIJSGlTflJTHHlG-S Lynch, and. Arthur R. Sandt, Serial Number 496,651, filed and provides a polemoistenmg device or attachment therefor,

which latter,-however, is capable of-use in.

pole puncturing machines generally.

In the use of pole puncturing machines. when the poles are dry, it has been found that the puncturing tools, even when made pointed or sharp, will cut or break the fibers of the pole and, in some cases, will even chip the pole. To prevent this, I provide a moistening device or attachment arranged to deliver onto .the pole over that zone that is to be, punctured, but in advance of thepuncturing operation, a moistening liquid, preferably water, which in the summer time will be cool but in the wintertime will be in the form of hot water or, in some cases, steam. e

In the accompanying. drawings, which illustrate the invention and wherein like characters indicate like parts throughout the several views, this improved moistening device is shown as applied to a pole puncturing machine of the type disclosed and claimed in the application above identified, and its application to this type of machine involves certain special novel features, as will hereinafter appear.

Referring to the drawings:

Fig. 1 is a fragmentary side elevation showing portions of the machine above referred to and illustrating the improved moistening device applied thereto;

Fig. 2 is a vertical section taken approximately on the line 2-2 of Fig. 1 and showing the parts on a larger scale than in F ig. 1; and

Fig. 3 is a fragmentary view partly in side elevation and partly in section show fiiccificaiion of Letters Patent.

ing the moisture controlling valve and operating connection therefor.

Of the parts ofthe pole puncturing ma chine, in so far as it is important for the purposes of this case to note the same, and using the same numerals that are applied thereto in the said application above identified, said parts are as follows: 7

The pole 3/ is placed upon av pole-carrying truck comprising a frame 17 having wheels 18 arranged to run on rails19., Tov support the pole free for easy rotation, the truck 17 is provided with transversely spaced edgewise aligned pole-supporting wheels 20. The numeral 21 indicates abel frame on which is supported an upstanding main frame 22. The, relatively heavy end portion of the pole, when delivered to the machine, will be supported by peripherally toothed pol'e-rotating and supporting wheels 23 of the mechanism.

The by the beam 741-, the anchored ally connected at end of which is pivot raised and lowered by a hydraulic cylinderand piston motor 76. The numeral '88 in" dicates a curved transversely extended rail secured to the extended end of the beam 74, and below this rail is a floating frame 89 suspended from said beam and rail 88 with freedom for slight lateral movements by devices including link structures 98 and 100, which supports are completely disclosed. in said pending application above identified. The numerals ].O3104t indicate. curved roller-equipped pole-engaging saddlebars thataresuitably connected to the floating frame 89.

The pole puncturing devices which are carried directly by the floating frame 89 include a plurality of casings 106 and cooperating reciprocating punches 118, which pole puncturing device is supported overhanging end of a;.-cantilever,

75 to the main frame Said beam74i', as shown, is arranged to be perforations a positioned to discharge directly onto the upwardly moving surface of the pole, so that the pole surface will be moistened before it is subjected to the punches. The extended end of this nozzle pipe a is closed but the other end thereof is shown as connected by a flexible hose 2) to a pipe a secured on and extended longitudinally of thebeam 74. This pipe 6 is connected by a short flexible hose cl to an upright pipe 6 that is secured on the main frame 22 and, as shown, is provided at its lower end with a normally closed drain valve f. The pipe 6 is connected to a water or moisture supply 9 that leads from a source of water or steam supply and is provided with a controlling valve h. The numeral 70 indicates a drip pan placed below the pole in position to receive the water dripped from the pole.

, s is evident, when the valve h is opened, water will run into the nozzle pipe to and will be spread onto the poleas above stated. As also above indicated, the water maybe warm or cold, according to the conditions of the weather, and might, in some instances, even be in the form of steam.

In actual practice, this moistening de vice has been found to very materially im} prove the action of the puncturing operation. It causes the punches to make holes in the pole by the separation rather'than by the cutting or breaking of the fibers of the pole, and forms punctures that will readily absorb creosote or other woodpreserving fluids by subsequent operationand which punctures, when the pole surface becomes well saturated with the preserving fluid, will nearly or quite close under the action of expansion of the wood.

1? preferably provide automatic connections for operating the moisture controlling valve h. This valve, in Fig. 3, is shown as in an open position and .itsprojecting stem is provided with an arm M that is connected by a link m to the beam 74:. To provide for adjustments or variations in movements given to the valve h, the arm ll and'link m are provided with longitudinally spaced perforations through which a nut-' and when said beam deliver moisture onto that zone of the equipped bolt or pin a is passed to pivotally' connect the same. I

The above arrangement is such that, when the beam 7 1 is lowered to'press the saddle bars 103 onto the pole and to bring the punches 118 into action, thelink m, 'operat ing through the arm M, will move the valve it into its open position shown. in Fig. 3, 7 1 is raised to lift the punches from working position, said link and armwill automatically move said valve into a closed position. Thisvautomatic'ally turns-on and cuts off the supply of moisture at the right times.

What I claim is: I v V 1. The combination with a machine comprising means forsupporting and rotating a pole, an overlying beam, a floating frame supported from said beam and powerdriven punches mountedframe, in combination with a mo'istening device applied to saidfloating frame and arrangedto deliver moisture onto that zone of the pole that is to be punctured, imme' diately in advance of the puncturing, opera tion. C

2. The structure defined in, claim 1 in which said moistening device is in the form of a perforated spraying pipe and in which there is aflfexible moisturespraying tube leading therefrom and supported in part by said beam.

3. The combination with a machine having means for puncturing the surface of a pole, of a moistening device arranged to pole that 18 to be punctured, immediately in advance of the puncturing operation, said on said floating" moistening device having aval've and con-1 nections for automatically operating "the same when the punching means is moved to and from'operative position.

4:. The structure defined in claim. 1 in which said moistening device includes a valve having a connection to said beam whereby it will be automatically operated by vertical movements of said beam.
